SPECIFICATION forming part of Letters Patent No. 445,871, dated February3, 1891.

Application filed September 26, 1890- Serial No. 366,275. (No model.) i

tivator attachment, and is designed to pre-' vent accidents occurring tothe plow or shovel by striking rocks, roots, or other obstructions; andwith this object in view it consists of a shoe pivoted to the end of theplow-standard and a peculiarly-constructed spring adapted to bear uponthe upper end of the shoe and hold the same in place, the shovel or plowbeing secured to the lower end of the shoe; and our invention consists,further, in certain details of construction and combination of partswhereby we produce an attachment which is simpler, cheaper, and moreeasily applied than similar devices now in use.

In the drawings, Figure 1 is a side view of our improved cultivatorattachment. Fig. 2 is a detail view of the springs, and Fig. 3 is a viewshowing the position the parts assume when an obstruction is met.

Referring to the drawings, 10 indicates the plow or cultivator beam, and11 the standard attached thereto. The standard and beam may be integralor separate, as desired, one of the chief points of our invention beingits adaptability to all patterns of plows and cultivators now in use. Ashoe 12 is pivoted near its upper end to the lower end of the standard11 by means of the bolt 13. The shoe 12 is essentially U- shaped incross-section, the closed side being placed foremost, and the upper endof said shoe is somewhat contracted, as shown, in order to fit moreclosely upon the end of the standard, and

provide a broad base for the attachment of plows, shovels, (to.

Near the upper end of the shoe, in both sides of the same, are form edthe apertures 14, which register with an aperture 15 in standard 11.A'break-pin 16 may or may notbe passed through these apertures, asdesired. A leaf-spring plate 17 is secured at its upper end to the underside of beam, the lower end of said spring bearing upon the upper end ofshoe. T 1e upper end of the spring has its edges bent up around the sideof the beam, as shown at 17, and said spring is secured to the beam bymeans of bolts 18, passing through the spring 17, resting against thebeam, and through a clip-plate 19, arranged upon the upper side of beam.At a point 17 just rear of the bolts 18, the springplate 17 is bentdownwardly at an obtuse angle, and continued straight until within ashort distance of the lower end of springsay at 17 -when said plate isbent outwardly and downwardly parallel with the shoe 12, the bent endbearing upon the upper end of shoe and holding the same in place. The

edges of the lower end of spring-plate are bent rearward, asat 17,adapted to embrace the front side of shoe and act as a guide for thesame.

The spring-plate 17 may be strengthened by any desired number of leaves19, said leaves being secured at their upper ends by the bolts 18, andextend along the straight portion of the plate 17 down as far as thebend 17, each plate being bent at 1.7 b the same as the plate 17.

With a plate constructed and arranged as described the shoe is braced bythe straight portion between 17 and 17, and, if desired, the break-pinmay be omitted, as any resisting force that will curve the straightportion of the plate 17 will break a wooden pin. The leaves 19, alsosliding on the bent end of plate, tend to brace the shoe.

From the above it will be seen that we provide an attachment that ischeap, simple, and easily applied, and one that performs additionalfunctions to those commonly in use by dispensing with the break-pin orextra springs.

Having thus described our invention, what we claim is 1. In a cultivatorattachment, the combination, with a beam and rigid standard, of a shoepivotally attached to the lower end of said standard, and a leaf-springthe central portion of which is straight, the end portions bent atobtuse angles to the central portion, the upper end being secured to theunder side of the beam, the lower end bearing upon the upper end of theshoe, the edges of the lower portion being bent rearwardly to partiallyembrace the front side of the shoe, all arranged and adapted to operatesubstantially as shown and described.

2. In a cultivator attachment, the combination, with a beam and rigidstandard, of a shoe pivotally attached to the lower end of saidstandard, a leaf-spring having a straight central portion, and the endportions bent at obtuse angles to the central portion, the upper endportion being secured to the under side of the beam, the edges of saidend portion being bent up around the sides of the bea1n,the lower endportion bearing upon the upper end of the shoe, the edges of said lowerend portion being bent rearwardly to partially em- I 5 brace the shoe,and an additional leaf-spring secured to the beam beneath the upper endportion and extending along the upper and central portions as far as thelower end portion, substantially as shown and described.
